can someone please review my code for Circle game
problem : Problem - D - Codeforces
my solution : ( first I let Ashish and Utkarsh travel vertically(along y axis till (number of moves)*k<=d ) then I switched them horizontally ( along x axis till (the condition x^2 +y^2 <= d^2 holds true and updated number of moves ++ ) finally if number of moves are even Utkarsh wins else Ashish wins ) here is my code :
#include <bits/stdc++.h>
using namespace std;
#define int long long
int32_t main()
{
ios_base::sync_with_stdio(false);
cin.tie(NULL);
int t;
cin>>t;
while(t--)
{
int d,k;
cin>>d>>k;
int m=k;
if(d%k==0)
{
if((d/k)%2==0)
{
cout<<"Utkarsh"<<endl;
}
else
{
cout<<"Ashish"<<endl;
}
}
else
{
int a = d/k;
a=a*k;
int b = d/k;
while(true)
{
if((d*d)>=(a*a)+(k*k))
{
b++;
k=k+m;
}
else
{
break;
}
}
if((b)%2==0)
{
cout<<"Utkarsh"<<endl;
}
else
{
cout<<"Ashish"<<endl;
}
}
}
return 0;
}
